    u(t) is called 60 times per second.
    t: Elapsed time in seconds.
    S: Shorthand for Math.sin.
    C: Shorthand for Math.cos.
    T: Shorthand for Math.tan.
    R: Function that generates rgba-strings, usage ex.: R(255, 255, 255, 0.5)
    c: A 1920x1080 canvas.
    x: A 2D context for that canvas.

First time this actually saves chars on dwitter...
u/joeytwiddle

Wow, that is the craziest approach I have seen to that problem! But I can't argue with a 2 char saving.
u/f8f82804

u/yonatan: genius!
u/username

I am very confused. Did I actually bring up shadowBlur again? Have never seen it on Dwitter before.
u/donbright

man this looks so cool.. the JoeyTwiddle effect is one for the books.
u/joeytwiddle

Here are some previous uses of shadowBlur: d/2723 d/3173 d/6820 d/6883 d/9608

Looks better with x.shadowBlur=j--/7 #glow
